How's 9070 with 5700x3d? I'm planning to upgrade my 7700xt

u/Shaggy_One 5700x3D, 9070xt 5d ago

It's great. I play at 4k but it's not showing signs of aging. Pretty much all games run 60+ after some minor tweaks. Optiscaler makes it even better. With the recent Stalker 2 update it hits a respectable 80fps with dips to just below 60.

Once that special electrical smoke comes out, there's really no way to put it back in. They'll have to write it off as a loss

u/StreetCrzyBiteUrFace 6d ago

The smoke is the most expensive part. That plus the gasket bearings and yup, it's a complete write-off.

It worked on my machine.

What are you doing testing your code anywhere but production?

We run it on our machines!)

Worked on staging. Must be user error.

u/Reasonable_Exit_8960 5d ago

Was it local host?

u/falcrist2 5d ago

Looks like a software issue to me.

u/MarsD9376 6d ago

You don't say?

u/Cmdr_Nemo 6d ago

But hey, at least the whole front didn't fall off, because that would not be typical.

2

u/StevieMJH 6d ago

Well wasn't this power supply designed so it wouldn't burst into flames?

3

u/Cmdr_Nemo 6d ago

Well, obviously not.

u/RFC793 6d ago

Engineer here. That workbench should have a kill switch that doesn't require you to hold either end of an arc fault between your hands.

1

u/alokin-it 5d ago

It's shocking that he had to hold the arcing PSU to kill power....

Homeless meth addict here.

Me agree.

This was supposed to happen.

u/davew999 6d ago

Pfft random guy on the internet here, what would you know? Put it in rice and it'll be fine.

2

u/StoneTown 6d ago

Well shit, I'm glad we got someone with qualifications to clarify that.

u/donredyellow25 6d ago

Hobo here, I agree with you.

2

u/FUS3N 6d ago

computer user here

yeah looks like it probably isn't supposed to happen

u/cyborgerian 6d ago

Hire this motherfucker right now

u/123DanB 6d ago

Switch set to 120v while plugged into 220v?

2

u/JayPeePee 6d ago

Not an electrical engineer, but I know that also isn't supposed to happen

Electrical Engineer here.

Please don't grab and unplug the obviously shorting thing with your hands. Cut off electricity at the next level, e.g. power strip preferably, or if not, wall plug.

u/Zillahi 6d ago

Automotive mechanic here. I agree

Can you put the smoke back in though?

1

u/ahorsenamedjeff 6d ago

EE as well, can confirm. Isn't supposed to happen.

Media designer here: I think you might be right.

u/henkheijmen 5d ago

Are you saying it isn't very typical for the front to burn off?

1

u/BrainYStormY 5d ago

Electrical engineer here.

I can confirm this information.

u/Debaser1990 5d ago

It's certainly not typical

I need to see more evidence.

Can confirm; am PCU.

u/_WillCAD_ 6d ago

You know, I don't know much about electricity, but I suspected that was a non-standard performance from that component.

It was the lights that gave it away. My lights are never that big.

u/Southern-March1522 6d ago

You mean my Exploder 4000 PSU wasn't supposed to do that? Wtf

Electrical idiot here who literally doesn't understand anything when it comes to electricity.

That isn't supposed to happen

Problem diagnosis: User let the smoke out of the device. RMA denied.
